Functional and aesthetic evaluation of adjacent tissue flap repairing defects of oral commissure area

Taking into account the differences between each reconstruction method, the Estlander flap is the preferred method for small and medium-sized defects, the McGregor and Colmenero flap can better restore motor function.The methods of repairing defects of the oral commissure area described in our study do not differ significantly in speech expression, flap tactile sensitivity, or aesthetic outcomes. Postoperative quality of life is higher in patients reconstructed with Estlander, McGregor and Colmenero flap repairing.
